Abstract

Alternatively to a cylindrical steel shell a sandwich shell was analyzed with regard to the stability. The sandwich shell consists of an inner and outer steel face, which are bonded adhesively to different core materials between them. Two grout and one elastomer core were investigated in this study. In comparison with linear buckling analyses the validity of a laminate composites shell theory was proven. The results showed a significant increase in shell stability for sandwich cylinders where the inner and outer steel faces were loaded up to the yield stress considering an optimized core thickness. In this case the core materials operated as full laminar stiffening and leaded to an increase of ideal buckling stresses. The shell stability can be optimized with the E-Modul of the core material additionally to the variation of core thickness. Due to the reached plastic buckling loads the combination of high strength steels is in principle possible to get shell constructions which will be optimized with regard to stability and weight. The theoretical investigations for the stability of sandwich cylinders will be continued with experimental investigations including axial compression tests in part 2.
